   The memory bloat is so bad, it is hard to use. Had to cap memory so it is not crashing my system. 25GB+
   (Fedora 43) Would be amazing if you could look into this 🙏

   Can you share any steps to reproduce, any pattern of when it happens, are you writing rust code (special ask because rust lsp eats a lot of mem)

   In terms of LSPs I got Typescript and Eslint.
   I also kicked out a plugin I was using to be sure.
   It feels like a memory leak FWIW.

   Could you give it a try with #9693 applied?

    I gave your branch a good go, unfortunately I kept running into bun crashes (not sure if related) so I could not really gather data for longer sessions.
    That being said, 1.1.28 shows improved memory handling. I can clearly see how the allocated memory is released again.

    Fix message history cleanup to prevent memory leaks in TUI

    That went in with 1.1.27 and sounds like what I am seeing.

    I've been experiencing this almost daily. Usually, I notice it rise to the upper 20s or 30GB. This morning, after leaving it up overnight, it got over 50GB... had to restart Activity Monitor for it to even register it.
    Also, not sure why I see opencode-cli rather than opencode, like other users show.

    Closing in favor of #20695 where we're collecting all memory-related problems. Please follow that issue for updates.
